Title: Discrete Fiber Optic Sensing Techniques for Structural Health Monitoring of Bridges
Author(s): Farhad Ansari
Publication: Special Publication
Appears on pages(s): 1-12
Keywords: Cracks; Damage; Fiber Optic Sensors; Structural Health Monitoring; FBG; Bridges; Stay Cables; Brooklyn Bridge
Abstract:From the very beginnings of time mankind has been intrigued with the potential applications of light and the possibilities that it could bring about. The origins of optical fibers probably go back to mid 19th century when the scientists tried to guide, bend, and transmit the light from one location to another. Now, optical fibers have found widespread usage in telecommunications as well as in medical and sensing applications. This article provides a summary review of principles involved in sensing with discrete optical fibers such as Bragg gratings and specific methods more prevalently employed in monitoring of bridges. The focus will be in application examples including monitoring of the masonry vaults of the Brooklyn Bridge, deformation of cable stays, and fiber optic accelerometers for testing of bridges.
